Description

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-1935 1.03 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the handling of ConfigFileUpload requests to the web management portal. The issue results from the lack of proper validation of a user-supplied string before using it as a format specifier.
